I'm going to grad school starting in the Fall and need a new notebook as my old Vaio is trashed. My desktop is very old too, so this will be my primary machine. I was hoping the new Macbook Pro's would come out before school starts the first week of September, but recent rumors/news seems to indicate that this may not happen. I will need a machine from day one, so my plan is to buy a Macbook that I will possibly sell on craigslist when the new MB Pro comes out. I am very budget conscious since I won't live with this machine long, so I was wondering if 2.1Ghz vs. 2.4Ghz makes much difference. I come from the Windows side, so my experience is that memory is more important in the real world. The price difference will be about $100 after upgrading the 2.1Ghz to 2GB of memory. I'm not worried about the slightly larger hard drive or combo vs. super drive. Am I correct that I won't see very much difference between the two based on the 300Mhz processing speed? My only other concern is resale value (would someone pay $100 more for the 2.4Ghz six months from now).
